To 1/ t Iwhom it may concern:

Bc it known that i, Josnr losnx'ri-IAL, engineer, citizen of Germany, residing at Munich, Bavaria, Germany, have invent-ed certain new and useful improvements in ll'olders for lVadiating- Apparatus; and l do hereby declare the following to be i full, clear, and exact description of the invention, such as will enable others skilled in the. art to which it appcrtains to make and `use the same.

Devices for irradiating bodies by means of X orRoentgcn rays, in which the compressive member, that is to say the part` or frame designed to hold in place the object to be irranliated, .is connected with the arms by ball and socket joints, the arms being in their turn mounted on sleeves slidingly arranged on pillars or supports, said arrangement allowing; of theI locking` of the freely movable compressive member in any desired position, are not new. But with sach devices at least four set-screws must. bc manipulated, this rcquiring considerable time.

'lf he aim of the present invention is to simplify and quicken the work of lockiiig,` in position a device of the kind mentioned above.

,Referent-fc being,` had to the accompanying i drawings, which show in cach case only one side or half of the entire device, the other fside being the exact counterpart, one form of construction is shown in Figure l in a side view and in Fig. 2 in a View from the rear; Figs. 3 and l are thc same views lfigs. l and but contain certain parts in section. Figs. 5 and illustrato a second form of construction, Fig. 5 being a side View and .Fig (S a plan view with certain parts in scction, and Fig. 'T a sidcz'elc 7ation of still another .nmditication 'lhe essential feature of this invention consists in the choice of suitable inner joints, thus making it possible to lock the entire de- ".'ice with the help of two hand screws only; hereby the time necessary to fix the compressive member in position is reduced to one half as compared with the devices in use formerly.

in the first form of construction, shown in Figs. l to el, these inner joints (i) arc in thc form of cross-joints, that isfdoublc oints with two axes at right angles to eachother;

lcach cross-joint: consists of two stirrups or forks (o, p), the one (o) being att-ached to the compressive member having the forn of a frame or ring (d), a portion only of 'which is represented and the other (p) to the arm (c). These forks (o, p) are pivoted to a center-'piece (y). If nowthe two outer joints (l) of the device be locked, these inner cross-joints will also become automatically locked, making special set-screws at said inner joints unnecessary; for as' soon as the varms (c) on each side of the compressive member or frame d are fixed in position, the peculiar construction of the inner joints (i), makes a further displacement of the compressive member impossible.

In the followinfr a suitable arranfrement of the outer joints is described. The arm (c) slides between the two cheeks (fr, s), the latter being suitably recessed to encompass said arm. These cheeks (r, c) are loosely arranged on the bolt (19, of which the .head is formed as a sleeve (u), encompassing and slidingly arranged on the pillar or support The other end of said lholt (z5) contains a screw thread on which` a nut (w) with handle (as) is arranged. The sleeve al is encircled byan outer concentric lsleeve n, adapted to slide on the same and also slidn'igly arranged on the pillar a. ythis sleeve yv is detached from but bears against the outer face of the cheek piece 1^, as slignrn.

The mode of procedure in' using this dcvicc is as follows: The compressive member is first adjusted in the desired position by hand and the nuts, (to) then tightened by means 'of their handles (au), thereby pressing the arms between the cheeks (7', But at. thc same time the two"l 'sleeves or collars (u, fa) are pressed in opposite ldirections against the support (c), thereby lockingthe entire joint together with "the arm (c) to said support. ln order 'to facilitate the unlocking of the cheeks,v small coil springs (y) are inserted in suitable'recesses in said cheeks, adapted to press them apart.

Figs. 5 and 6 illustrate a form of construction in which. the outer joints are similar to the joint (Z) described above, but the inner joints consist of ball and socket joints. In order inv this case t'o also attain the same advantages as in the former construction, namely, the locking of the entire device with only two screws, the following arrangement has been made.

' The inner ball and socket joint (il) is fitted with a -set screw. (7), having a head (8) in the form of the crank. A rod {l0} the outer joint is at one end pivotally attached to the pin (0) of said crank, the other end being pivotl ed at (ll) to the nut (fw) of the outer joint l (Z). It the handle (x) be now moved in l the direction ot' the arrow (Fig. 5), not only j will the outer joint (Z) be locked but rod (10) will also lock the inner ball and socket jointl by means of the set screw (7 lVhen l) is unlocked, the inner ball and socket joint will likewise be unlocked by the rod (l0).

. It will be obvious that the connecting rod (l0) may also be pivoted -to the handle (ai) ot the outer joint tl), as shown in Fig. 7,

or any other suitable -contrivance may be used for insuring conformity of action of the outer and innei` joints.

It will be seen from the above that in all the forms shown in illustration of my. invention, the supporting pillar a, and the connecting rod c are slidingly arranged Within a clamp composed of the cheek pieces r, '8, on the one hand and the sleeves u, o arranged to slide one within the .other on the other hand, and that the said pillar and arm are adapted to be' simultaneously locked ior unlocked by means, which under the preferable form of' my invention, as shown, consist of the screw stud passing through the cheeks and the nut, w, bearing against the inner cheek piece. By this means when the arm c has slid to the proper extent through the clamp constituting the outer joint to permit it to take the proper inclination required by the position or height of the holding frame, and the clamp has slid to the proper height on the pillar a, the clamp is locked by one movement of the nut'lw or the handle As it is desirable to lock or unloclothe universal joint at i or z" constituting the inner joint of the apparatus, the additional locking meansjshown in Figs. 5 to 7 has been l l l l i devised, said locking means consisting of the connecting rod l0 connected as above'l described to the first clamp locking device 1 on the one hand andthe locking means for i the universal joint, comprising the clamp .screw 7 and the crank arin 8, on the other;

Thereby both the clamp and the universal joint are simultaneously locked or unlocked, as the case may be.

The advantages of an apparatus thus constructed will be apparent when it is considered that, in exposing a part of the body to X-rays, the operator must press the compression member 0l on the 4part to be treated iii such a way that the soft portions 'are compressed thereby reducing the thickness of the l part to be penetrated by said rays. In s o i manipulating thc instrument the proper pol s ition for the compressing member is difierent for each individual case and can only be found by trial, and for this purpose the saidv compressing member must, within certain limits, be free to move in every direction.

When the proper position of the compress# ing member has been thus obtained, it is necessary 'that the same can be quickly, and byk a simple manipulation, secured Vagainst movement iii any direction, so that the crosssection of the parts to be irradiated will reinain unchanged during the entire irradiating process. This result is attained in an eminently satisfactory manner by this apparatus in which, as above set forth, the coinpressing member when once in position is locked against movement by a single turn or twist of the locking handle What I'claim as my invention vand dcsire to secure by Letters Patent, is:

1. In a holder for irradiating apparatus,
